Get the salt out: Conventional polyamide desalination membranes suffer from low chlorine tolerance, leading to short membrane life. Using newly synthesized sulfonated copolymers prepared by direct copolymerization of disulfonated monomer, chlorine‐tolerant desalination membranes (see picture) showing high flux and high salt rejection were developed.
Das Aus für's Salz: Übliche Polyamidmembranen zur Entsalzung werden leicht durch Chlor angegriffen, doch sulfonierte Copolymere, die durch eine direkte Copolymerisation mit einem disulfonierten Monomer entstehen, bieten sich als chlorbeständige Alternative an. Mithilfe solcher Membranen (siehe Bild) gelingt die leistungsstarke Entsalzung bei hohem Durchfluss.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
